The means for mounting the drum on the yoke are so constructed that the same is capable of being turned in a vertical plane end for end and also turned about the axis of the drum. In the construction shown in Figures 1, 2, 8, and 4 this is accomplished by means which comprise a lower rotatable clamping head 29 having preferably the form of a disk and engaging one end of the drum and a clamping head 30 having preferably the form of a crow foot and adapted to engage with the opposite end of the drum. .The clamping head 29 is provided on its inner side or face with centering ribs or projections 31 which engage with the respective head of the drum within the rim 32 thereof and the toes 33 of the other clamping head engage in like manner with the other head of the drum within the rim 32 thereof, whereby the drum being cleaned is securely held against lateral displacement on the clamping heads. The lower clamping head is pivotally mounted on the fixed arm 20 of the yoke by means of a spindle 34 arranged on the lower clamping head and projecting outwardly therefrom in line with its axis and journaled in a bearing 35 on the arm 20, and a clamping and pivot screw 86 working in a threaded opening in the detachable arm of the yoke and having a conical end 87 which engages with a correspondingly shaped seat 38 on the central part of the outer side of the clamping head 30. By means of this clamping and pivot screw the drum may be clamped between the heads of the chuck sufficiently firm to hold the same pivotally in place and it also permits of adapting the clamping means to variations in the lengths of the drum within certain limits. The pivot screw may be held in place after adjustment by means of a lock nut 381 mounted thereon and engaging with the outer sides of the arm 21, as shown in Figure 2. In order to adapt the machine for cleaning drums which vary considerably in length this can be accomplished by placing a spacing sleeve 39 of appropriate length on the spindle 34 between the head 29 and the arm 20, as shown in Figures 1 and 2.

The means for turning the drum vertically end for end and also turning it about its own axis are constructed as follows:

The numeral 41 represents a longitudinal driving shaft arranged with its front part in the hollow shaft while its rear end is journaled in a bearing 42 on the rear standard. Arranged in front of one end of the yoke cross bar is an intermediate shaft 421 which is journaled in bearings 81, 82, on the adjacent parts of the yoke so that the axis of this shaft is parallel with the axis of the drum to be cleaned and at right angles to the axis of the longitudinal shafts 40, 41. Motion is transmitted to this driving. shaft by a belt passing around a driving pulley 44 secured to the driving shaft. The latter and the intermediate shaft are caused to turn together by intermeshing bevel gear wheels 45, 46 secured to the adjacent ends of these shafts. Motion is transmitted from the intermediate shaft to the lowerclamping head of the yoke by a driving gear pin ion 47 arranged on the outer end of the intermediate shaft and meshing with a gear rim 48 on the edge of the lower clamping head. This driving pinion is preferably elongated so as to permit this clamping head to be moved toward and from the axis of the yoke within certain limits and still without disturbing the driving connection between this head and the intermediate shaft.

Motion at reduced speed is transmitted from a belt driven pulley 49, which is loose on the shaft 41, to the hollow shaft 40 which connects with the yoke, by a counter shaft 50 journaled lengthwise in bearings 51, 52 on the lower parts of the frame standard and having a gear wheel 53 which meshes with a gear pinion 54 on the driving shaft 41, and a gear pinion 55 011 the counter shaft meshing with a gear wheel 56 on the hollow shaft 40, as best shown in Figure 2.

Between the driving pulleys 44, 49, an idle pulley 57 is mounted loosely on the driving shaft. 1

Means are provided for holding either of the driving shafts 40, 41 against turning, this being satisfactorily accomplished by two brake drums 58, 59 arranged on the pulleys 44, 49, respectively, two brake bands 60, 61 embracing these brake drums, respectively, and each band being connected at one end to the adjacent part of the main frame, two brake shafts 62, 63, journaled transversely in suitable bearings on the lower part of the main frame and each provided'with a pull arm 64 which is connected with the free end of one of the brake bands, horizontal shifting rods 65, 66, connected respectively at their rear ends with operating arms 87, 88, on the brake shafts, and upright operating levers 67, 68 pivoted at their lower ends on the front part of the frame base and connected, respectively, with 'ins iem1 the "front ends'of the shifting rods" 65, 'These operzftlng lever mzty be hldin' their operative 'po'sition by lofc'king pewls o -dogs (59, arranged onlthe sides of these levers andada'p ted 'to' engage with 'mtxihetseg- 'Inents 71, 72011 the adj a'centrpart' o'fth'e' main fra'm'e. v I

A'belt shifter is provided for shifting the driving belt from the central idle 1 pulley segment'78 on the frame.
